That's pretty important - sounds much more like a vintage unit if you do that (more mids, a little smoother up top, and just generally better). Up to 22nF on the output cap still sounds good with the Tungsrams.

I don't think that Dave uses the 15nFs to compensate for anything. Many vintage units had 15nFs, his own Vox included. He likes that sound a lot!

Mine had 10nF and all the schematics I'd seen had 10s, so I assumed wrong. A-B-ing with a set on Tungsram AC125s on the breadboard, 15nF got me much closer to the sound of the original. I had assumed drift/wide tolerance to be the reason (although differences in the way the transistors clip will come into it too).

Right, different transistors do sound slightly different. My Valvo AC125s sound quite a bit brighter than my Philips OC75s. Your Philips AC125s should work great for a MKII, btw. Make sure you use the OC75 variant of the schematic with 10k on Q1's base and 47k on Q2's collector.

Did you use the schematic that came with the transistors? That tends to cause most of your issues. Small Bear biases Q3 at 4.5V, which makes it sound trebly and brings down the level. They use a 100k at Q1's base which takes a lot of range from the attack pot when used with OC75s.

Impedance problems with pedals/buffers in front of a MKII are quite common..

Cheers. So they are basically unavailable as of now! Shame, shame, shameee. PEDALENCLOSURE.COM PEOPLEGIVE US A BUZZ

If it's a steel "Z wedge" enclosure, I have an unfinished one, undrilled (and unmarked apart from a couple of tiny tentative drill marks that would disappear under a finish). I bought without realising I didn't have the cojones (or drill bits) to drill steel, and you or anyone else is welcome to it for £10 + the cost of postage to wherever you are.

Call me sentimental, call me dumb.. But it's time to rehash the first post in this here thread.. And check this auction:

Looks like I'm going to have to see if I can buy myself a trio of OC75s on eBay, since I've got a PCB kit for a Marshall Super Fuzz which I might build soon, I've already built a good sounding Mk II with some OC81Ds......

There it is... Marshall Super Fuzz justification to add to my pedal collection. I am wondering if Jimi actually used that pedal on any recordings...

Where did you get that PCB kit from? I was thinking about using a layout from Sinner but I like PCBs if I can get them

I bought the Marshall Super Fuzz PCB kit online from Pigeon FX, the PCB is etched on Phenolic and comes with all the vintage style components you need minus the Transistors, I'd definitely recommend buying one of these kits, they're pretty good quality......

Nice! That will save me time finding the mojo parts... Thanks!

You're welcome, let me know how your build goes......

Follow you, follow me: i bought those very same dsi oc81d that you have like one year ago, never got around to make the build, the other day i fired the pro mk ii thread you posted, and right now i am building a mk ii with those dsi's into a WHITE PIgeon FX MK I enclosure. Good grief.
